U.S. exports of Spark-Ignition Reciprocating or Rotary Marine Propulsion Engines, N.E.S. (SITC 71332) totaled $5.3M in August 2026.
Importers of Spark-Ignition Reciprocating or Rotary Marine Propulsion Engines, N.E.S. paid $16K in duties in August 2026, an average duty rate of 2.27% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Spark-Ignition Reciprocating or Rotary Marine Propulsion Engines, N.E.S. imports of $695K in August 2026 ran 35% below the year-to-date monthly average of $1.1M.
Last updated: August 2026 dataSpark-ignition reciprocating and rotary engines used for marine propulsion — other than outboard motors — include inboard gasoline engines and Wankel-type rotary units fitted in pleasure craft, patrol boats, and specialty vessels. The 'not elsewhere specified' qualifier means this heading captures marine spark-ignition engines that do not fall under the outboard motor category (SITC 71331), making the installation configuration and vessel type key classification factors. EPA marine engine emissions compliance under 40 CFR Part 1045 applies to these engines when imported for use in US waters.

Outboard motors (71331) are fully self-contained units — engine, gearbox, and propeller integrated in a single transom-mounted assembly. Engines under 71332 are spark-ignition marine propulsion engines designed for inboard or other non-outboard installations, where the engine is separate from the drive and steering components. The physical configuration and installation method are the determining factors.
No — both reciprocating piston and rotary (Wankel) designs are explicitly included in SITC 71332 provided they are spark-ignition marine propulsion engines not classified as outboard motors. The engine architecture does not change the heading, though it may affect applicable EPA certification pathways and spare-parts sourcing considerations.
